The hull of the Quiltra Queleual-class is shaped like a rectangular brick, a compromise between atmospheric capability, accessible and usable volume and ease of manufacture. There are six engine clusters in the aft section; all of which can fire forward for braking and other maneuvers; the two upper engines though ports in the upper hull, the lower four engines through forward nozzles that are closed by a hinged hatch when not in use. There is the normal number of attitude thrusters spread over the ship. The aft bulkhead has airlocks along its periphery for access to the auxiliary vessel hangars. The locks, two in the upper half and one in the lower half, are large enough to admit Frandlar Tiluvo trans-orbital transports. There are three more large hatches in the rest of the ship, one in the nose and two in the sides. These hatches cover the entrances to multiple internal decks, and can be used for voluminous cargo. The bottom of a Quiltra Queleual contains extendable elevators and ramps leading to the lower decks; cargo, or, in the troop carrier configuration, troops, can be embarked or disembarked directly onto a surface. It is not necessary for the ship to actually land on a planet in order to do this, typically the anti-gravity systems are used to keep the ship aloft while the embarkation/disembarkation takes place.
Internally, there are seven main deck levels, one half deck and several large hangars. The command center, engineering section, Reflex furnaces, fold drive systems and other related machinery are all located on the double-height center deck. Also on this deck are the quarters for the actual ship's crew and their facilities. The Gnerl air group is housed on the half deck in the uppermost centre half of the Quiltra Queleual, and launch through chutes at the sides. The other six decks, three above and three below the central deck, can be configured as needed by installing prefabricated inner sections. These sections can be made up of cargo holds, fuel tanks, crew quarters, mecha hangars, cold and warm storage holds, ammunition magazines or other, more specialized inner hull parts. It is not necessary for all sections on different decks, or even sections on the same deck, to be of an identical type. This gives the class maximum flexibility, for each ship can be configured or reconfigured as needed to any degree desired. For instance, a ship can carry additional fuel tanks on all decks (tanker version), or supplies on several decks and troops on the other decks (landing ship version), or fuel and cargo, and this in any configuration required. However, such custom configurations were rare, the Zentraedi usually sticking to one of their standard versions. The auxiliary vessels carried by the Quiltra Queleual are hangared in the aft section, just forward of the aftmost pressure bulkhead.
Technology and Combat CharacteristicsEdit
The armament is limited, as the Quiltra Queleual-class was not designed to stand in the battle-line. There are ten torpedo tubes forward of the Gnerl launch bays. As the scout-sized vessels the Quiltra Queleual was designed to hold off cannot mount as extensive anti-torpedo batteries as larger ships, this number of launchers sufficed. The cannon armament does not follow the normal Zentraedi lay-out of heavy fire forward and medium fire on the other arcs, rather, the turrets are mounted, like the defensive missile system, for spherical coverage.
As a tanker, the Quiltra Queleual-class carried more than twice its normal fuel load, and could refuel numerous reconnaissance frigates, several heavy cruisers, or one force or fleet flagship. However, as it was very unusual for Zentraedi ships to burn their fuel tanks dry (standard procedures called for a minimum supply of 65% maximum capacity), one tanker usually sufficed to refuel a normal Zentraedi flotilla. The landing ship configuration could carry 12,000 troops, their weapons and supplies, and the means to land these on a planet; however, this number of troops was rarely needed save for planetary invasions. Usually, troops were added to the tender/underway replenishment combination; the resulting fleet support configuration could carry 4000 troops and their weapons and surface transports, sufficient stores to supply a normal Zentraedi deployment through several battles, and serve as a tender to the smaller Tou Redir scouts and the various auxiliary ships in the flotilla. Thus, a normal Zentraedi fleet deployment included two to four Quiltra Queleual-class vessels, divided equally between the fleet support and the tanker version.
Most of the Quiltra Queleual-class was brought to the Earth's solar system with the Grand Fleet, as it was expected due to the massive ammunition and fuel expenditures. As a result, most of the class was destroyed in the Zentraedi Holocaust over Earth, with the survivors rapidly losing power due to protoculture depletion.
